Yinz remember that time one time when Pittsburgh Steelers' linebacker James "Silverback" Harrison turned into a real-life superhero? And no, we're not referring to his considerable on-field prowess. We're talking about the time he played the unexpected role as a field security guard.

Let's set the scene: It was a typical Sunday afternoon in Cleveland, Ohio. The Browns and Steelers were facing off and things were heating up on the field. The crowd was electric. And then it happened: a Brownie's fan decided to take center stage. Dude burst onto the field - much to the dismay of the players and the chagrin of the security staff.

James Harrison. And he wasn't having any of it. Enjoy:
